BACKGROUND

The various embodiments and aspects described herein relate to an accessory for a truck bed to elongate a length of the truck bed.

Trucks have beds that come in a variety of sizes. By way of example and not limitation, the truck beds may be a short bed or long bed. The short bed may serve the purposes of its owner a majority of the time but at certain times, the owner may require a slightly longer truck bed to haul larger or longer objects. In this regard, the owner may let down his or her tailgate and allow the objects to hang out of the back side of the truck bed when hauling the long object. In doing so, the object becomes a safety hazard in that other vehicles and pedestrians may not see the elongated object hanging out of the truck bed and may inadvertently hit the object causing injury to the person and/or damage to the object.

Additionally, the objects configuration may not be conducive to easily tying the object down in the truck bed. The tailgate is typically lifted upward in order to trap the object within the truck bed so that even if the object slides in the truck bed, the object would still remain within the truck bed.

Accordingly, there is a need in the art for an accessory for a truck bed.

BRIEF SUMMARY

A pick up truck elongator in the form of the tailgate is disclosed herein. The factory tailgate may be replaced with a replacement tailgate that can be pivoted downward to elongate the length of the factory truck bed. The replacement tailgate has a front shell that can be pivoted upward to function as the new tailgate when a rear shell of the replacement tailgate acts as the support to elongate the length of the factory truck bed. Left and right side panels may be unfolded in order to form an enclosure with left and right side walls of the truck bed. Additionally, the rear shell can be fabricated from first and second telescoping panels that allow the user to further expand the factory truck bed.

Alternatively, the original tailgate or replacement tailgate may act as the support to elongate the length of the factory truck bed. Side panels are tucked away in the cavity adjacent a rear side of the left and right truck side bed walls. The panels are folded out and engaged to the upper surface of the tailgate in order to retain objects placed in the truck bed within the truck bed.

DETAILED DESCRIPTION

Referring now to the drawings, a replacement tailgate 10 a for a bed 12 of the truck 14 for the purpose of elongating the pickup truck is shown. The tailgate 10 a may replace the factory tailgate and enable the user to elongate the factory length 16 of the truck bed 12 of the truck 14. The tailgate 10 a can elongate the factory length 16 of the truck bed 12 about a height 18 of the truck bed 12 or an elongated length 20 (see FIG. 11). The tailgate 10, 10 a can also be secured to standard factory latching mechanisms of the factory installed truck bed so that no or little modification to the truck bed 12 is necessary in order to retrofit the truck 14 with the tailgate 10. Alternatively, the factory tailgate may be used to elongate the factory length 16 of the truck bed 12 of the truck 14.

Referring now the FIGS. 1-8, the tailgate 10 is shown as being deployed to elongate the length 16 of the truck bed 12 to the height 18 of the truck bed 12. In particular, the tailgate 10 has cover 22. The cover 22 is disposed on top of upper ends 24, 26 of front and rear shells 28, 30 of the tailgate 10. The cover 22 prevents objects from being inadvertently disposed between the front and rear shells 28, 30. The front shell 28 functions as the tailgate when the factory length 16 of the truck 12 is elongated by the height 18 of the truck bed 12, as shown in FIG. 8. The rear shell 30 functions as a bottom support for elongating the length 16 so that longer objects 34 can be placed in the truck bed 12 and secured therein by the tailgate 32. Pivoting the cover 22 about the upper end 26 of the rear shell 30 may enable the front shell 28 to be pivoted about the rear shell 30.

After pivoting the cover 22 to the open position as shown in FIG. 2, the user may release the tailgate 10 from the left and right side walls 36, 38 to lower the front and rear shells 28, 30 to elongate the factory length 16 of the truck bed 12. As discussed above, the cover 22 may be attached and configured to the tailgate 10 so that pivoting of the cover 22 to the open position enables pivoting of the front shell 28 about the rear shell 30. In this regard, the cover 22 can be pivoted to the open position either before or after the tailgate 10 is traversed to the down position, as shown in FIG. 3. Moreover, it is also contemplated that the ability of the front and rear shells 28, 30 to be pivoted about each other can be independent of the position of the cover 22. The cover 22 can be held in the closed position, as shown in FIG. 1 or in the open position as shown in FIG. 2 with a detent or other latching mechanism.

Once the tailgate 10 is pivoted downward, the front shell 28 can be pivoted upward as shown in FIG. 4. The pivoting angle 40 can be limited to between about 90° and about 270° (see FIG. 5), as shown in FIGS. 4 and 5. The pivoting angle 40 can be limited by way of a detent or other mechanism known in the art or developed in the future. When the front shell 28 is pivoted 270°, the user can slide objects 34 into the bed then lift the front shell 28 upward to trap the objects 34 in the truck bed 12, as shown in FIG. 6.

The front shell 28 may have a height 42 (see FIG. 4) equal to about the height 18 of the tailgate 10. Alternatively, the height 42 of the front shell 28 may be greater than or less than the height 18 but is preferably about equal to the height 18 of the tailgate 10.

As shown in FIG. 7, left and right side panels 44, 46 can be rotated outward and secured to the left and right side walls 36, 38 of the truck bed 12 with the latching mechanism 48. The latching mechanism 48 may be secured to the standard receivers on truck beds so that no or little modification to the truck bed 12 is needed. By securing the latching member 48 to the standard receivers on the truck bed 12, the pivoting angle 40 of the front shell 28 is locked to 90°. Also, the elongated length 20 is set to the height 18 of the tailgate 10. Objects 34 placed within the truck bed 12 remain secured therein by way of the front shell 28 and the left and right side panels 44, 46. The left and right side panels 44, 46 may remain in the un-deployed state as shown in FIGS. 4 and 5. By way of example and not limitation, the left and right side panels 44, 46 and the front shell 28 may have magnets and/or detents that hold the left and right side panels 44, 46 against the front shell 28. Other mechanisms are also contemplated such as detents, latches, etc.

In a further feature, the tailgate 10 may be used to elongate the factory length 16 of the truck bed 12 greater than the height and up to an elongated length 20. To this end, referring now to FIGS. 9-14 the rear shell 30 may be fabricated from telescoping first and second telescoping panels 50, 52. By extending the telescoping first and second panels 50, 52, the truck bed 12 can be elongated by length 54 (see FIG. 10) which is greater than the height 18. The second telescoping panel 52 may be traversed between the retracted position, shown in FIG. 3 or the elongated position, shown in FIG. 10. The second telescoping panel 52 may be retained in the retracted position or elongated position by way of a detent or other mechanism known in the art or developed in the future.

Once the second telescoping panel 52 is traversed to the expanded position as shown in FIG. 10, the front shell 28 may be pivoted downward so that the front shell 28 hangs downward as shown in FIG. 11. In this way, objects 34 can be slid onto or off of the truck bed 12. Once objects 34 are placed in the truck bed 12, the user can traverse the front shell 28 so that the front shell 28 is 90° with respect to the rear shell 30, shown in FIG. 12. The left and right side panels 44, 46 can be rotated outward as shown in FIG. 13. Moreover, left and right elongating panels 56, 58 can also be rotated to close the gap 60 between the left and right side panels 44, 46 and the left and right side walls 36, 38 of the truck bed 12. Once the latches 60, 62 are secured to the receivers, objects 34 placed on the truck bed cannot slip out of the truck bed 12 due to the front shell 28, left and right side panels 44, 46 and the left and right elongating panels 56, 58.

The front and rear shells 20, 30, left and right side panels 44, 46 and the left and right elongating panels 56, 58 may be fabricated from a variety of materials including but not limited to carbon fiber, steel, fiberglass, plastic, aluminum, and other materials known in the art or developed in the future.

The tailgate 10 described herein has been describe as a replacement to a factory tailgate. However, it is also contemplated that the tailgate may be offered as original equipment from the factory or manufacturer.

Referring now to FIGS. 15-20, a second embodiment of the apparatus and device for extending the factory length 16 (see FIG. 16) of the truck bed 12 of the truck 14 is shown. In particular, the replacement tailgate 10 a may be attached to the truck bed 12 by attaching the tailgate 10 a to the standard attachment mechanisms provided in the truck 14. By way of example and not limitation, the tailgate 10 a may be pivotally attached to a rear portion of the truck bed 12. The tailgate 10 a may pivot about pivot axis 70. Preferably, the pivot motion of the tailgate 10 a may be limited to 90° as shown in FIGS. 15 and 16. The tailgate 10 a when in the vertical orientation may be in the locked position and unlocked only when the user grips the handle 72 and releases the latching mechanism between the tailgate 10 a and the factory latching mechanisms in the side walls of the truck bed 12 of the truck 14. When the tailgate 10 a is pivoted downward as shown in FIG. 16, the tailgate 10 a and more particularly an upper surface 76 of the tailgate 10 a may be coplanar with an upper surface 74 of the truck bed 12 so that the tailgate 10 a now extends the length 16 of the truck bed 12 plus the tailgate 10 a. Objects 34 placed within the truck bed 12 may be retained therein with a plurality of driver-side vertical panels 78 and passenger-side vertical panels 80 which are stacked, folded, and stored into cavities 82, 84 formed by the side walls 36, 38 and the top ledge 86, 88 of the left and right side walls 36, 38. It is also contemplated that the plurality of driver-side vertical panels 78 and passenger-side vertical panels 80 may be stacked, folded and stored adjacent to but not within a cavity of the sidewalls 36, 38.

The passenger-side vertical panels 80 a-c and the driver-side vertical panels 78 a-c may be pivoted out as shown in FIGS. 17-20. In particular, panels 78 a, 80 a may pivot around 90° about vertical pivot axes 90, 92. The vertical panels 78 a, 80 a may extend out until the vertical panels 78 a, 80 a are parallel to left and right side edges 94, 96 of the tailgate 10 a, shown in FIG. 18. The vertical panels 78 a, 80 a may be secured in this position by means known in the art or developed in the future. By way of example and not limitation, the vertical panels 78 a, 80 a may have detents or other latching mechanisms that may be used to attach the vertical panels 78 a, 80 a to the tailgate 10 a.

The panels 78 b, 80 b may be pivoted until the panels 78 b, 80 b are generally parallel with the back edge 98 of the tailgate 10 a. The panels 78 b and 80 b may be pivoted about vertical pivot axes 104, 106. Likewise, the vertical panels 78 c, 80 c may be pivoted to close the opening 108 as shown in FIG. 20. The vertical panels 78 c, a-c may be pivoted about vertical pivot axes 110, 112. The bottom edge portions 100 of the panels 78 b, c and 80 b, c may have a rubberized weather stripping 102. The weather stripping 102 may be received into a groove 104 formed in the upper surface 76 of the tailgate 10 a. The panels 78 b, c and panels 80 b, c may be held in position by way of latching mechanisms known in the art or developed in the future. By way of example and not limitation, these latching mechanisms include but are not limited to detents, over center latches, etc. Moreover, the disposition of the weather strip 102 of the panels 78 b, c and 80 b, c also help to retain the panels 78 b, c, 80 b, c parallel to the back edge 98 of the tailgate 10 a. The two vertical panels 78 c, 80 c may also be latched together with the latching mechanism known in the art or developed in the future. In this manner, objects 34 placed in the truck bed may roll around in the truck bed 12 but will not roll out of the truck bed 12 because the objects 34 are blocked by the vertical panels 78 a, b, c and panels 80 a, b, c.

The tailgate has been described as having third vertical panels 78 c and 80 c in order to close the back edge of the tailgate. However, it is also contemplated that the second vertical panels 78 b and 80 b which are rotatably attached to the first vertical panels 78 a and 80 a may be sufficiently long so that distal ends of the second vertical panels 78 b and 80 b can be latched to each other with the latching mechanism that latches the third vertical panels 78 c and 80 c together, as discussed above.

In a variant of the second embodiment of the tailgate 10 a, the original factory tailgate may be utilized in conjunction with the left and right vertical panels 70 a, b, c and vertical panels 80 a, b, c. To this end, the hinge that allows the panels 78 a, 80 a to be pivoted about vertical pivot axes 90, 92 may be locked in the deployed state as shown in FIG. 18. Likewise, the hinge that enables the panels 78 b, 80 b to pivot about vertical pivot axes 104, 106 may be locked in the deployed state as shown in FIG. 19. Optionally, the hinge that enables the panels 78 c, 80 c to pivot about vertical axes 110, 112 may be locked in the deployed state as shown in FIG. 20 or alternatively the panels 78 c and 80 c may freely rotate out the vertical pivot axes 110, 112 and be locked in the deployed state as shown in FIG. 20 by way of the latching mechanism that secures the panels 78 c to 80 c and vice versa.

In the second embodiment, the passenger-side vertical panels are made up of three panels 80 a-c. The driver-side vertical panels 78 are also made up of three vertical panels 78 a-c. It is also contemplated that the panel 78 a and 80 a which are parallel to the left and right edges 94, 96 of the tailgate 10 a may be made up of one or more panels that are rotatably attached to each other. The panels 78 b-c and 80 b-c may also be each made up of one or more panels that are rotatably attached to each other.

Referring now to FIGS. 21-27, a third embodiment of the pick up truck elongator 200 for extending a factory length 16 of a truck bed 12 of the truck 14 is shown. The pick up truck elongator 200 may be factory installed or installed by a retail owner of the truck 14. The elongator 200 may have a replacement tailgate 202 that replaces the factory tailgate if the pick up truck elongator 200 is installed by the retail owner of the truck 14. The replacement tailgate 202 may be mounted to the truck bed in the same manner that the original factory tailgate is mounted to the truck bed. Although shown only in phantom, the replacement tailgate 202 may have cables that hold the tailgate 202 in a horizontal position or coplanar with a floor 204 of the truck bed 12 when the replacement tailgate 202 is in the down position as shown in FIG. 22.

To deploy the pick up truck elongator 200 to extend the factory length 16 of the truck bed 12, the tailgate 202 may be traversed from the up position as shown in FIG. 21 to the down position, shown in FIG. 22. In the down position, an extension panel 206 of the tailgate may be pivoted up and out as shown by rotational arrow 208 about pivot axis 210. The pivot axis 210 is offset inward from an upper edge 212 of the tailgate 202. The offset distance 214 may be about 2 inches to about a full height 216 of the replacement tailgate 202. Preferably, the offset distance 214 is about 6 inches inward from the upper edge 212. A height 218 of the extension panel 206 may be equal to or less than a difference between the height 216 of the replacement tailgate 202 and the offset distance 214. In the figures, the extension panel 206 is shown as being pivotally attached to the replacement tailgate 202. However, it is also contemplated that the extension panel may be pivotally attached to the floor 204 of the truck bed 12. In this regard, the pivot axis 210 will be moved over the truck bed 12 and a height 218 of the extension panel 206 may be sufficiently long to extend beyond the upper edge 212 of the replacement tailgate 202 when the replacement tailgate 202 is in the down position and the extension panel 206 is pivoted out. As a further alternative, it is contemplated that the extension panel 206 may simply be an add-on that is mounted to the tailgate 202 and/or the floor 204. As a further alternative, it is contemplated that the extension panel 206 may slide out from the tailgate 202 beyond the upper edge 212 of the tailgate 202. The sliding out of the extension panel 206 may be accomplished by embedding the extension panel 206 within the tailgate 202 or placing the extension panel 206 on top of the tailgate 202 so that the extension panel 206 is parallel with the upper surface of the tailgate 202 when the tailgate 202 is in the down position as shown in FIG. 22.

The replacement tailgate 202 may also come with two sets 220, 222 of the plurality of panels 224, 226. The first set 220 of the plurality of panels 224 may be mounted to the driver side wall 228 of the truck bed 12. The second set 222 of the plurality of panels 226 may be mounted to the passenger side wall 230. The driver side wall and passenger side wall 228, 230 of the truck bed 12 may have interior side hollow cavities in which the first and second sets 220, 222 of the plurality of panels 224, 226 may be stored. The hollow cavities in the sidewalls 228, 230 may be formed by the taillight and may be disposed directly behind the taillight 232. When the first and second sets 220, 222 are in the stored position, the first and second sets 220, 222 are disposed within the cavities in the sidewalls 228, 230 behind the taillights 232. To deploy the plurality of panels 224, 226 of the of the first and second sets 220, 222, the housings 234, 236 may be traversed medially so that the plurality of panels 224, 226 can be slid out and disposed vertically above the tailgate 202 and the extension panel 206, as shown in FIG. 25. Although the figures and description explain that the housings 234, 236 are stored in the cavities then traversed medially in order to deploy the elongator 200, it is also contemplated that the housings 234, 236 may be fixedly attached to the sidewalls 228, 230 in the position shown in FIG. 24. In that fixed position, the plurality of panels 224, 226 can be slid out over the tailgate 202 and the extension panel 206.

In the figures and description, it is explained that the elongator 200 elongates the truck bed 12 to a distal edge 238 of the extension panel 206. However, it is also contemplated that the extension panel 206 may be an optional component of the elongator 200. In this regard, the plurality of panels 224, 226 would slide out over the tailgate 202 then be pivoted inward to close off the back end of the extended truck bed portion of the elongator 200. The panels would be aligned to the edge 212 of the tailgate.

With the first and second sets 220, 222 and more particularly the housings 234, 236 traversed medially inward as shown in FIG. 24, the plurality of panels 224, 226 may be telescoped outward, as shown in FIG. 25. In this exemplary embodiment, the plurality of panels 224, 226 may each have four panels each 240, 242, 244 and 246 and 240 a, 242 a, 244 a, and 246 a. Panels 240, 242 and 240 a, 242 a are slid out of the housings 234, 236. The panels 244, 246 and 244 a, 246 a are slid out of the panel 242, 242 a. Also, these panels 244, 246 and 244 a, 246 a may be pivoted about panels 242, 242 a about vertical pivot axis 248, 250 and pivoted in the direction of rotational arrows 252, 254. Preferably, the panel 246, 246 a are disposed in panel 244, 244 a when the panels 244, 244 a are being rotated. After the panels 242, 242 a are rotated about pivot axis 248, 250, the panels 244, 244 a are parallel to the distal edge 238 of the extension panel 206. If the extension panel 206 was not utilized, then the panel's lengths could have been adjusted so that panel 242, 242 a would have been pivoted about pivot axis 256, 258 so that the panels 242, 244 and panels 242 a, 244 a would have been parallel and aligned to the upper edge 212 of the tailgate 202.

With the panels 244, 244 a parallel to the distal edge 238 of the extension panel 206, the panels 246, 246 a may be slid out from the panels 244, 244 a and lock to each other in order to form the enclosure of the truck bed 12, as shown in FIG. 27. The panels 246, 246 a are shown as being slid out from the panels 244, 244 a, however, it is also contemplated that the panels 246, 246 a may be pivoted out from a side of the panels 244, 244 a about pivot axes 260, 262.

When the elongator 200 is deployed, as shown in FIG. 27, brake and taillights 264, 266 may be mounted to the panels 244, 244 a, 246, 246 a as a separate add-on or may be embedded therein and wired to the automobile's electrical system so that the brake and taillights 264, 266 work when the blinkers and brakes are being actuated by the driver.

Referring now to FIGS. 28-31, a fourth embodiment of the elongator 300 is shown. The elongator 300 has housings 334, 336 that house a plurality of panels 324, 326. The plurality of panels 324, 326 include panels 340, 340 a, 342 and 342 a which telescope outward in unison with the extension panel 306 as the elongator 300 is being deployed.

The extension panel 306 is stored on the floor 304 of the truck bed 12 when the elongator 300 is not deployed or in the stored position. The extension panel 306 may be disposed on top of the floor 304 or below the floor. The extension panel 306 may be secured to the panel 342, 342 a so that the plurality of panels 324, 326 telescope outward in unison with the extension panel 306.

More particularly, the elongator may be similar to a drawer of a cabinet which may be pulled out in order to extend the length of the truck bed. The elongator 300 may be locked into the closed position as shown in FIG. 28. However, when it is desired to lengthen the length of the truck bed, the user may unlock a lock 384 of the elongator so that the elongator may be deployed as shown in FIGS. 29-31. The lock 384 may be unlocked with a handle 327. When the handle is lifted up, then the lock 384 is unlocked and when the handle which is spring biased down is released so as to return to the down position, the lock 384 may be locked again so that the elongator 300 does not extend or retract back in. When fully deployed, the elongator 300 may provide an additional 1 to 6 feet (preferably an additional 2-4 feet) of additional length to the truck bed 12. FIG. 30 illustrates the elongator 300 in the fully deployed position. However, it is also contemplated that the elongator 300 may have a plurality of intermediate positions between the closed and fully deployed positions as well. The elongator may be pulled backward and locked with a locking mechanism into positions by increments of 6 inches or other factor (e.g., 2, 4, 8, 10 inches) until the elongator 300 is fully deployed.

The housings 334, 336 of the elongator 300 may be fixed in position as shown in FIG. 29. The housings 334, 336 are positioned medially from the taillights 232 so that the plurality of panels 324, 326 may be telescoped outward or backward as the elongator 300 is being deployed without having to reposition the housings 334, 336 medially (as discussed in relation to FIGS. 23 and 24 above). The housings 334, 336 may house the panels 340, 342, 340 a, 342 a. As the tailgate 302 is being moved backward, the panels 340, 340 a, 342, 342 a may be telescoped out. Moreover, the extension panel 306 may also be retracted outward. The extension panel 306 may be one piece or a plurality of panels that telescope outward. For example, the extension panel 306 may have two panels that telescope outward as the tailgate 302 is being moved backwards to deploy or lengthen the truck bed. When the elongator is fully deployed as shown in FIG. 31, the elongator 300 may be locked in position by way of a plurality of detents or other mechanism. The tailgate 302 may be disposed in the down position, as shown in FIG. 31 in order to access the truck bed 12. Additionally, the extension panel 306 may be supported by a support structure 368 (e.g., telescoping 1 beam) attached to the truck bed (e.g., underside thereof) and extendable out from the truck bed as the extension panel 306 is being deployed. The support structure 368 may be telescoping and provide the necessary support to hold weight placed on the extension panel 306 when in the deployed position. The support structure may be located below the floor of the truck bed and under the extension panel 306 so that the truck bed remains generally flat and does not interfere with loading a flat plywood, lumber, furniture, or other objects into the truck bed.

The tailgate 302 may also have taillights 370 which are the primary taillights 370 which will be seen when the elongator 300 is extended into the deployed position as shown in FIG. 30. When the elongator 300 is deployed, the taillights 232 on the sidewalls 228, 230 are not fully visible or are blocked by the elongator 300 and itself. Taillights 370 may be electrically connected to the electrical system of the truck so that the taillights 370 operate in the same fashion and time as taillights 232. The electrical wires may be routed through the panels 340, 342, 340 a, 342 a. The taillights 370 may be aesthetically blended in with the taillights 232 so that the taillights 370 appear to be one with the taillight 232 when the elongator 300 is in the undeployed position (see FIG. 28). By way of example and not limitation, a height and position of the taillights 370 may be aligned to the height and position of the taillight 232, as shown in FIG. 28.

The support structures 368 may be secured to the truck bed 12, and more particularly to the floor 304 of the truck bed 12. The support structures 368 may be disposed under the floor 304 and slide out from under the floor 304 of the truck bed 12 when the elongator 300 is deployed. When the elongator 300 is traversed to the deployed position, the support structures 368 may still be firmly secured to the floor 304 of the truck bed 12. The support structures 368 are described as being attached to the floor 304 but also it is contemplated that the support structures 368 may be attached to the frame or other structural components of the truck 14. The support structures 368 may each be a single elongate piece that slides in and out of the sleeve 380 attached to the frame, or floor or a structural component of the truck. The single elongate piece extends out with the extension panel 306 of the elongator 300. The support structures 308 may also be telescoping.

The single elongate pieces of the support structures 368 may have a rack 372 that is paired to a pinion 374. The pinion 374 may be rotatable clockwise and counterclockwise directions with a motor 376 (e.g., stepper motor) attached to a shaft 378 which is also attached to the pinion 374. The stepper motor 376 moves the support structure 368 within the sleeve 380. The support structure 368 is slidable within the sleeve 380 and the sleeve 380 is fixedly secured to the truck 14, floor 304 or the frame of the truck 14. The sleeves 380 provide the support so that when a heavy object is loaded on the deployed elongator 300, the extension panel 306 and the panels 324, 326 do not sag downward. The support structures 368 are also fixable or movable or associated with extension panel 306. In other words, when the extension panel 306 moves out, the support structures 368 may be extended. The support structures 368 may extend the full length of the extension panel 306 as shown in FIG. 31 or may be only partially under the extension panel 306 as needed. The stepper motor 378 may be operable by way of a control panel 382 located on or adjacent to the truck bed 12. The control panel 382 is operative to control the clockwise or counterclockwise rotational movement of the stepper motor 378 in order to deploy or retract the support structures 368 and also the elongator 300. The control panel 382 may traverse the elongator 300 to the deployed position by turning the pinion 374 which traverses the support structures 368 to the extended position. When the support structure 368 is attached or connected to the extension panel 306 and extension panel 306 is connected to the plurality of panels 324, 326, extension of the support structures 368 also traverses the elongator 300 into the deployed position. The stepper motor 378 provides an incremental adjustment and lock to the amount of extension provided by the elongator 300. In this regard, the stepper motor 378 may provide for incremental adjustments to the extension of the elongator less than 6 inches per increment.

The stepper motors 378 may be used to hold the position of the elongator 300 in its deployed state. However, additional or alternative locking mechanisms (e.g. detents and clamps) may be utilized in order to further secure the position of the elongator 300 in the deployed state. The deployed state may be when the elongator 300 is partially (see FIG. 28) or frilly extended out. The support structures 368 may each have the rack and pinion configuration along with the stepper motor 378, 380 discussed above in order to provide an even traversal of the elongator from the retracted position to the deployed position. One control panel 382 may control the operation of both stepper motors 378 each of the support structures. Additionally, the stepper motors 378 may be controlled with controls (e.g. button, switch or electronic panel) located in the cabin of truck 14.

Referring back to FIG. 30, the tailgate may have two different handles 327 and 329. Handle 327, as discussed above, may be operative to lock and unlock the lock 384 that fixes the position of the elongator 300. Additionally, the handle 327 may also be operative to rotate the stepper motors 378 in either the clockwise or counterclockwise direction in order to extend the elongator 300 when the handle 327 is lifted up or to retract the elongator 300 when the handle 327 is traversed downward and pushed inward as shown by directional arrow 331. When the inward force is removed, the handle 327 may return to its normal position and stop rotation of the stepper motors 378. The handle 327 may essentially be a switch that operates one or both of the stepper motors 378 and the lock 384. Handle 329 is operative to let the tailgate down as shown in FIG. 31.
